Description
Abstract
                            The spatial data was obtained from the Texas Water Development Board and are current as of 2002. The river basin data was originially created by the United States Geological Survey. The attributes were modified to include basin name, area, and identification information.
                          
Purpose
                            This layer contains river basins in Texas. This boundary file was specifically designed for small to medium scale thematic mapping and analysis.

                          
Supplemental Information
                            Metadata was not created for use with this shapefile originally.  This metadata is probably incomplete, but is meant to assist with using this dataset.
